I noticed when we upgraded from 7.2 to 7.5 that the first time a window is opened, if the ‘enabled’ property binding of any control has been used, it is changed to ‘componentEnabled’. The message in the Output Console warning of this change has a couple of typos in it. ‘Retargeting’ is spelt wrong and it took us a while to work out what ‘binging’ was 
Retargetting property binging for renamed property. button.enabled is now button.componentEnabled
Thanks for the heads up. We’ll get this fixed.
And here I was thinking it had something to do with adult beverages...
